Subject: [PATCH 1/2] EDoc: Allow user defined macros to be functions

This makes them equal to the builtin ones, and allows for neat things
like linking to the offical docs page:

```
man_doc_macro(MacroArg, _Line, _Env) ->
    {ok, Pattern} = re:compile("([^:]+):([^/]+)/(\\d+)"),
    {match, [Module, Function, Arity]} = re:run(
        MacroArg, Pattern, [{capture, all_but_first, binary}]
    ),
    lists:flatten(io_lib:format(
        "<a href=\"https://erlang.org/man/~ts.html#~ts-~ts\"><code>~ts</code></a>",
        [Module, Function, Arity, MacroArg]
    )).
```
